RSQL Builder for MongoDB Methods

The RSQLBuilderMongoDB class provides many methods to build the desired RSQL string.

Initialization

constructor(options) – Initializes a new RSQLBuilderMongoDB instance.

Comparisons Operators (Defining Conditions)

equal(selector, value) - Appends a condition selector == value. notEqual(selector, value) - Appends a condition selector != value. lessThan(selector, value) - Appends a condition selector =lt= value. lessThanOrEqual(selector, value) - Appends a condition selector =le= value. greaterThan(selector, value) - Appends a condition selector =gr= value. greaterThanOrEqual(selector, value) - Appends a condition selector =ge= value. in(selector, values) - Appends a condition selector =in= (values). notIn(selector, value) - Appends a condition selector =out= (values). like(selector, regex, options) - Appends a condition selector =regex= value = options. notLike(selector, regex, options) - Appends a condition selector =notregex= value = options. regex(selector, regex, options) - Appends a condition selector =regex= value = options. notRegex(selector, regex, options) - Appends a condition selector =notregex= value = options.

Expression Grouping (Organizing Conditions)

group(builder) - Wraps the conditions from another RSQLBuilderMongoDB instance in parentheses for grouping.

Logical Operators (Combining Conditions)

and() – Appends the logical AND operator ;. or() - Appends a logical OR operator ,.

RSQL Builder Composition (Combining Multiple RSQL Queries)

concat(builder) – Appends all expressions from another RSQLBuilderMongoDB instance to the current instance. merge(builders) – Merges multiple RSQLBuilderMongoDB instances into grouped conditions.

RSQL String Management (Finalizing the Query)

toString() - Returns the generated RSQL query string. isEmpty() – Returns true if the RSQLBuilderMongoDB instance has no expressions; otherwise, returns false. reset() – Clears all expressions, resetting the RSQLBuilder instance.
